I guess it depends on where you got the image from. 

In the case of <a href="https://registry.hub.docker.com/u/eddelbuettel/docker-debian-r/" rel="nofollow">these docker containers of mine from the Docker Hub</a> you can use 
<a href="https://github.com/eddelbuettel/docker-debian-r.git" rel="nofollow">this link from the right hand side of the webpage</a> to follow it to <a href="https://github.com/eddelbuettel/docker-debian-r" rel="nofollow">this github repo containing the Dockerfile(s)</a>.

I do not think there is a command to "unassemble" a container / image and get back the instructions which made it.

<blockquote>

</blockquote>

No, considering you have commands like <a href="https://docs.docker.com/engine/reference/commandline/export/" rel="nofollow"><code>docker export</code></a> / <a href="https://docs.docker.com/engine/reference/commandline/import/" rel="nofollow"><code>docker import</code></a> which allows to flatten an image:

<pre><code>docker export &lt;containerID&gt; | docker import - &lt;imagename&gt;
</code></pre>

The resulting image would be build from a container, and include only one layer. Not even a <code>docker history</code> would be able to give clues as to the original images and their Dockerfile which where part of the original container.

You can use combinations of two docker commands to achieve what you want:

<pre><code>docker inspect &lt;image&gt;
</code></pre>

and 

<pre><code>docker history &lt;image&gt;
</code></pre>

Or you can use this cool service to see how that image being generated, each layer is a command in your docker file:

For the images you create image metadata (labels) can be used to store Dockerfile
 <a href="https://docs.docker.com/engine/userguide/labels-custom-metadata/" rel="nofollow">https://docs.docker.com/engine/userguide/labels-custom-metadata/</a>

Initial solution was proposed here <a href="https://speakerdeck.com/garethr/managing-container-configuration-with-metadata" rel="nofollow">https://speakerdeck.com/garethr/managing-container-configuration-with-metadata</a>

This approach of storing Dockerfile is not very efficient - it requires container to be started in order to extract the Dockerfile.

I personally use different approach - encode Dockerfile with Base64 and pass such encoded string using external arguments to set image label. This way you can read content of Dockerfile directly from image using inspect. 
You can find detailed example here: <a href="https://gist.github.com/lruslan/3dea3b3d52a66531b2a1" rel="nofollow">https://gist.github.com/lruslan/3dea3b3d52a66531b2a1</a>

Is it possible to get back the docker commands which were run to produce a given docker image? Since each line of a docker file should map to a single layer, it seems this would be possible, but I don't see anything in the docs.

是否有可能恢复为生成给定的docker图像而运行的docker命令？由于docker文件的每一行都应该映射到一个层，这似乎是可能的，但我在文档中看不到任何东西。
